【 摘 要 】

As real-time embedded systems become more complex, there is a desire to use these systems on higher performance commercial off-the-shelf (COTS) components. However, worst case execution times (WCET) are unreasonably high on these components, due to contention amongst resources. Past work has introduced the Predictable Execution Model (PREM) to solve this issue, but unfortunately, the time required to port existing code bases to this model is too high. Light-PREM is a tool that aims to extend this framework by automating certain processes that previously had to be done by hand. This thesis goes over the interface, implementation and preliminary results of two different implementations of Light-PREM.
